具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请提出一种感应式加热的气雾生成装置，在一个实施例中的构造参见图1所示，包括：
腔室，可抽吸材料A例如烟支可移除地接收在腔室内；
作为磁场发生器的电感线圈L，用于在交变电流下产生交变磁场；
感受器30，至少一部分在腔室内延伸，并被配置为与电感线圈L感应耦合，在被交变磁场穿透下发热，进而对可抽吸材料A进行加热，使可抽吸材料A的至少一种成分挥发，形成供抽吸的气溶胶；
电芯10，为可充电的直流电芯，可以提供直流电压和直流电流；
电路20，通过电连接到可充电的电芯10，并将电芯10输出的直流，转变成具有适合频率的交流再供应到电感线圈L。
根据产品使用中的设置，感受器30呈插入可抽吸材料A内部进行加热的片状或销钉形状；优选实施中，具有大约15毫米的长度，大约6毫米的宽度和大约1毫米的厚度。
在又一个优选的实施例中参见图2所示，感受器30a还可以被构造成圆筒状的形状；在使用时其内部空间用于接收可抽吸材料A，并通过对可抽吸材料A的外周加热的方式，生成供吸食的气溶胶。
在本申请的一个实施中，感受器30的构造可以参见图3所示，包括：
金属本体31，用于在变化的磁场穿透下发热，进而加热可抽吸材料；在优选的实施中，金属本体31采用不锈铁、镍钢、坡莫合金等包括铁或镍等磁导性能优良的合金材料；
保护层32，形成于金属本体31的表面，并比金属本体31更光滑。
在实施中，保护层32是具有表面微纳结构的保护层32。表面微纳结构的材料，在显微镜下是表面具有大量顶端呈略微凹陷的乳突，凹陷部分充满空气进而即可在保护层表面形成纳米级厚的空气层；因而一方面烟渣、灰尘等固体物质较难突破空气层直接浸润到保护层32的表面，另一方面气溶胶冷凝油、水汽等液体粘附在保护层32表面时由于最小直径(约1毫米)大于微纳结构而在自身表面张力的作用下形成球状体而从感受器30上滚落，即“荷叶效应”。
在保护层32的表面，烟渣、气溶胶冷凝油、水汽等有机污染物会自动聚集在一起，而不会粘结在涂层表面。在可抽吸材料A例如烟支抽完后拔出的过程中，烟渣、气溶胶冷凝油、水汽等会随着烟支一起被拔出来，而不会在感受器30部件上形成顽固的粘附或沉积。
在更加优选的实施中，通过具有表面微纳结构的保护层32的水的静态接触角大于120度，可以使得气溶胶冷凝油、水汽等液体极易在表面滚动进而提升防粘附的效果。
实施中，保护层32采用的可具有以上微纳结构的材质，比如是含有氟聚合物的复合材料，比如采用水性聚氨酯(WPU)中加入疏水性较强的聚四氟乙烯(PTFE)乳液后喷涂固化制备成的WPU/PTFE合金树脂；又比如由纳米金属氧化物、氮化物等通过1,6-己二胺辅助液相法配位化学原理在液相中合成的无机微 纳结构材料。
为了使保护层具有更高的硬度以及自身热稳定性，在更加优选的实施中，保护层32采用由纳米陶瓷成分与有机聚合物制备的纳米陶瓷复合材料。
在一个实施例中比如采用，具有高硬度的表面微纳结构的材料比如以纳米TiO2和聚四氟乙烯(PTFE)微粉、水性氟碳树脂制备的水性纳米TiO2/PTFE氟碳复合材料、或是聚四氟乙烯/Al3O2复合材料、或者是聚四氟乙烯/Al3O2-TiO2复合材料。
在优选的实施中，采用以无机纳米陶瓷如氧化铝、氧化硅、氧化钛、氧化锆、氮化铝、氮化锆等的粉末，与有机聚硅氧烷如甲基硅油、二甲基硅油、乙基硅油等混合制备的复合纳米陶瓷复合材料。通过采用有机聚硅氧烷作为助剂在纳米无机陶瓷固化的化学变化中，通过Si-C键结合并通过C-C键进行链接，有一部分碳链嵌入内部、而含硅元素的另一端露在表面形成疏水表面；因而在形成表面微纳结构的同时，还能改变表面的疏水性。
在更加优选的实施中，为了保证纳米陶瓷复合材料的稳定性，控制有机聚硅氧烷占保护层32中重量比低于5％。
以上的纳米陶瓷复合材料的保护层32的厚度介于25～35μm；并且保护层32的GB/T6739-2006热态铅笔硬度为6～8H，其中热态铅笔硬度测试中热态温度为GB标准300度。
进一步为了便于对采用以上具有表面微纳结构的感受器30的在强度、防粘附、耐受性能的进步性进行验证，以下通过具体实施例对制备的感受器30进行示例和结果说明。

进一步图16所示的SiO2-Al2O3/PTFE复合材料的保护层32的截面形貌中，并不是整体均匀的分布；具体PTFE粉末因质量轻、比重小、粘度较大，并在等离子焰流外缘停留的时间短，在喷涂过程中沉积于偏表层，最终形成图16所示包括完全熔融的和部分熔融的SiO2-Al2O3颗粒及PTFE的形貌结构。

S10，48H盐雾测试：配置5％盐水置于盐雾机内，然后把盐雾机内温度设置为35℃开始喷雾，持续48小时；
结果中，标准SS430不锈铁材质的48H盐雾测试表面形成较淡并可视的锈斑点，J85坡莫合金材质能通过48H盐雾测试。

S30，防烟渣粘附测试：抽吸第5～6支烟时，陶瓷釉层表面开始具有肉眼显著可见的烟渣和冷凝油的凝聚结块(块状面积大于4mm2)，口吹和晃动无法脱落，需要用酒精棉球擦拭；
